Need help deploying performance?
Chalk Labs sets up agents like this inside real teams: connected to your tools, tested on your data, with a human in the loop where it matters.
Install
Works with Claude Code, Claude apps, Codex, Cursor, Gemini CLI, GitHub Copilot, VS Code, OpenCode, Goose, Windsurf. Read the repository before you give any tool access to your data.
npx agentmarket install skill/yousofdavamkar-performance
Asks which of your tools to add it to (Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI, Claude Desktop) and shows the change first. See https://agentmart.dev/cli.

SKILL.md (first lines)
# Performance Measure before optimizing and compare the same scenario afterward. Identify whether the bottleneck is network, main-thread work, rendering, memory, or server response. Prefer removing work, shipping less client JavaScript, using platform capabilities, and fixing asset delivery before adding caching or memoization complexity. Protect interaction readiness, layout stability, and meaningful content. Report the measurement method, environment, before/after values, and uncertainty. Do not claim improvement from code shape alone.
